'Snow White' Trench - Sol 43 (True Colors; credits: NASA)

Caption NASA:"This image was acquired by NASA's Phoenix Mars Lander's Surface Stereo Imager on Sol 43, the 43rd Martian Day after landing (July 8, 2008). This image shows the trench informally called "Snow White".

Two samples were delivered to the Wet Chemistry Laboratory, which is part of Phoenix's Microscopy, Electrochemistry, and Conductivity Analyzer (MECA).
The first sample was taken from the surface area just left of the trench and informally named "Rosy Red". It was delivered to the Wet Chemistry Laboratory on Sol 30 (June 25, 2008). The second sample, informally named "Sorceress", was taken from the center of the "Snow White" trench and delivered to the Wet Chemistry Laboratory on Sol 41 (July 6, 2008)".
